The difference between 201 stainless steel and 304 stainless steel
1. Specifications: Commonly used stainless steel plates are divided into two types: 201 stainless steel and 304 stainless steel. The actual composition is different. 304 stainless steel is of better quality but more expensive, and 201stainless steel is worse. 304 stainless steel is imported stainless steel plate, and 201stainless steel is domestic stainless steel plate.
2. The composition of 201 stainless steel is 17Cr-4.5Ni-6Mn-N, which is a Ni-saving steel type and a substitute steel for 301stainless steel. It becomes magnetic after cold processing and is used in railway vehicles.
3. 304 stainless steel is composed of 18Cr-9Ni, which is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc.
4.201 stainless steel has a high manganese content, and the surface is very bright with dark brightness. The high manganese content makes it easy to rust. 304 stainless steel contains more chromium, has a matte surface and does not rust. You can compare the two together. The most important thing is the difference in corrosion resistance. The corrosion resistance of 201 stainless steel is very poor, so the price is much cheaper. And because 201 stainless steel contains low nickel, the price is lower than 304 stainless steel, so the corrosion resistance is not as good as 304 stainless steel.
5. The difference between 201 stainless steel and 304 stainless steel is the nickel content. Moreover, the price of 304 stainless steel is relatively expensive now, but 304 stainless steel can at least guarantee that it will not rust during use. (You can experiment with potions)
6. Stainless steel is not easy to rust because it forms chromium-rich oxide on the surface of the steel body to protect the steel body. 201stainless steel material is a high-hardness stainless steel with higher carbon and lower nickel than 304 stainless steel.
